make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

This invention relates to bag-filling machines, and consists substantially in imrovements in the construction of machines for filling bags with measured quantities of material and gumming andsealing the bags after they are filled. To accomplish these results, we have constructed andcombined in this machine, mechanism substantially comprising an adjustable bag-holder for holding fiat paper bags in. an upright position, a rotatable adjustable measuring device; a hollow, vertically reciprocating seedcarrier, ada ted to enter the outermost bag in the bagolder, remove it therefrom and carry it downward into a position to be gummed and sealed; mechanism for opening said seed-carrier preferably as it starts upward out of the bag; adjustable mechanism for actuating the seed-carrier adapted to vary the traverse thereof; vertically adjust.- able gri ping mechanism to grip the lower end of t e bag when it has been moved to its lowermost position, hold it while the-seedcarrier is being withdrawnand while the bag. is being gummed and sealed, and afterward release it; a gumming mechanism adapted to move the to of the bag against the sealing anvil and ho d it there and gum it; a "ealingjaw to turn the bag-flap over and seal it down upon the shorter ply of the bag; and an air-blast mechanism for blowing dust from the mouth of the bag while it is being gummed and sealed. These and other features of this invention are hereinafter set forth and explained, and illustrated in the accompanying drawings in which:

of the machine. On uprights A A thereon is mounted a bag-holder, the side posts B B of which are mounted in grooves a a in the tops of the standards A A Right and lefthand screws 0/ a (see Fig. 3) engage the lower ends of said side-posts B B, whereby they can be moved toward and away from each other to accommodatedifierent widths of the bags.

C, and the upper parts of said side-posts B are slotted to permit of the vertical adjustment of the upper side bars I) b of the bagholder to accommodate the same to different lengths of the bags C. The front ends of the side bars I) b and b b are also provided with inwardly projecting studs 1) b -(see-Figs. 1 and 2) to engage the outermost of the bags 0. Above he front end of the bag-holder there is a slotted transverse bar B upon which lip-holders b are adjustably secured and adapted to engage the upwardly projecting flap of the outermost of thebags C in the bag-holder. This transverse bar B is mounted on the machine frame so as tobe vertically adjustable, whereby the lip-holders b thereon may be adapted to engage the flaps of bags of different lengths placed in the bag holder.

Between the front ends of the base bars B B of the bag-holder there is pivoted a spring-actuated flap B which, in its normal position, is on a horizontal plane with the tops of the base bars B B of the bag-holder, and extends outward into the path of the vertical traverse of the seed-carrier hereinafter described, and operates to support the I the further downward traverse of the seed-' lower end of the outermost of the bags C, until the seed-carrier has entered the bag and passed down into the bottom thereof, when carrier presses the flap B downward and out of its path, and as the seed-carrier travels i of the bag-holder is mounted a sliding bar D,

. able screws D D and on the front end thereof is pivoted a vertically adjustable follower D. In this follower D there is a vertical slot (1 and on the follower D there are horizontal arms (1 d vertically adjustable on,the follower D, by means of set screwsd passing through the slot 1; and in the arms (1 d there are adjustadapted to contact with the backs of the bags 0 and move them forward in the bag-holder against the studs d and the lip-holders 6 In order to make the follower D press harder against the upper ends of the bags 0 than it does against the lower ends, a spring D is provided which acts between the sliding bar D and the follower D to normally press the upper part of the follower D forward, so

as to constantly bringthe more or less open upper end of the outermost bag 0 into the path of thedownward travel of the lower end of the seed-carrier, hereinafter described.

The bar D and the follower D are moved forward against the bags by means of a cord (1 attached to the rear end of the bar and passing over pulleys d and d to aweight D (as clearly shown in Fig. 1). From the above description it is obvious that the mechanism described "is readily adjustable so as to operate to move different sized bags forward'in the bag-holder.

Su ported on a vertical extension A of the uprig t A and upon the vertical guides hereinafter .described, is a seed-receptacle E (clearly shown in Fig. 1). This receptacle is oblong, and a portion 0 of its bottom is transversely semi-circula and circular longitudinally, and is provided with a door e by means of which the seed receptacle can be cleaned out. At the front end of the receptacle is a discharge nozzle E through which measured quantities of seed or other material ,are discharged as hereinafter described.

At the upper art of the seed-receptacle E there is mounte a shaft E having arms 6 e thereon, and upon these arms are removably mounted adjustable measuring cups E E having semi-circular lips E under the discharge ends thereof, whereby, as the cups E are rotated so as to discharge their contents, the lips Etdirect it into the discharge nozzle E. This measuring mechanism is rotated by means of a sprocket wheel E on the shaft E from which a sprocket chain e? extends to a sprocket e on the crank-shaft of the machine hereinafter described.

In operation the cups E are adjusted to dip u the proper quantity of seed, or if from the c araeter of seed other sizes of cups r e necessary, they can-be secured in place on the arms e 6 and adjusted to measure the desired quantity of seed, and as the machine operates, a measured quantity of seed is dip ed up and discharged into the nozzle E, each time the seed-carrier, hereinafter described, reaches its uppermost point of traverse.

The seed-carrier of this machine consists of a hollow, somewhat conically-shaped, shell, the upper part F of which is open and adapted to pass up over the outside of the seedreceptacle nozzle E as the seed-carrier nears The lower ually to an obtuse point f, and the other section, F is hinged at its upper end to the section F, and extends downward with substantially the same taper and contour as the section F, nearly to the point f thereof, so as to close u on the, section F, and form a closed she I, and is adapted to open back from the section F, substantially as the bill of a bird opens. The features of this seedcarrier are clearly shownin Figs. 4 and 5. On the upper part of the sectionF of the seedcarrier, there is an upwardly projecting arm f provided on its upper end'with ,a roller f and between the arm f and the part F of the seed-carrier there is a spring f 3 which operates on the arm f to keep the section F normally closedagainst the section F, as shown in Figs. 1 and 5. On the downwardly projecting arm G, secured to the seed-receptacle there is mounted another arm G centrally pivoted to the arm G, at g, and provided at its upper end with a retracting spring g, and at one side of the lower part of the arm G there is adjustably secured thereto, a vertical camshaped bar G so shaped and located that when the seed-carrier travels through its downward traverse, the roller f on the arm f passes behind the cam-shaped bar G2 moving the lower end of it forward, the spring f 3 meanwhile operatin against the arm f to keep the part F o the seed-carrier closed 'upon the part F thereof, during the downward traverse of the seed-carrier. -As the seed-carrier nears the lowermost point of its traverse the roller f asses ofl of the outside of thelower end of t e cam-bar G and the spring y then restores the bar G to its normal position, so that when the seed-carrier starts on its upper traverse the roller 2 on the arm f engages the inside of the curved lower end g of the cam-bar Gr and is thereby gradually moved inward so as to open the se'ed-carrier as it moves upward out of the bag, retaining it open as shown in Fig. 4 until after it is withdrawn from the bag, thus allowing the seed in the seed-carrier to pass out of it into the bag as the seed-carrier moves upward; the seed-carrier is retained in this en position until the roller f 2 (passes off of t e upper end 9 of the cam-bar when the spring f operates on the arm f to close the seed-carrier, as illustrated in Fig. 1.

In operation, actuated as hereinafter described, the lower end f of the seed-carrier, when it arrives at the uppermost point of its traverse, is directly above the open end of the outermost of the bags 0, the fla' of which is slightly turned back by the lip-liolders b and as the seed-carrier moves downward the pointf thereof passes into the outermost bag etween the upturned flap and the shorter ply thereof, and as it moves downward detaches the bag from the bag-holder, turns the flap B on which the lower end of the bag rests, downward, and carries the bag down to the position where it is to be gummed and sealed, and as it starts upward outof the bag,

the seed-carrier is opened and discharges the seed therein into the bag. It is obvious from the foregoing description that so-called bags-openers are entirely dispensed with and not used in this structure,

the same being wholly unnecessary to the operation thereof. The mechanism by means of which the seed-carrier is o erated consists substan-.

tially of vertica guides H H suitably mounted on the machine frame between which there is a vertically sliding cross-head H having thereon a laterally projecting arm Hi, to which an arm F on the seed-carrier is adjustably secured. From the lower end of the cross-head H apitman h extends downward to the end of an arm h, the opposite endofwhich is pivoted on a stud A at the .rearof the machine frame.

The arm h is reciprocated by means of a pitman I, pivoted thereto at an intermediate point, and extending to a wrist-pin adjustably secured in a crank-disk I mounted on a shaft I suitably mounted in the machine frame, and actuated as hereinafter set forth.

The pitman I is made longitudinally adjust' able, and the wrist-pin I is also made adjustable in the crankdisk I for conveniently varying the traverse of the seed-carrier when desired, as is necessary when bags of varying lengths are used.

To receive the lower end-of the bag when it is carried down by the seed-carrier into position to be gummed and sealed, we provide a vertically adjustably gripping mechanism, referably mounted on a vertically adjusta 1e funnel J through which the filled and sealed bags are discharged from the machine. This funnel J extends down through an opening a in the frame A, and set-screws a passing through the ledge a on the frame hold it firmly at any elevation desired, as

clearly shown in Fig. 7. The upper end 3' of the rear wall J of the funnel 1s preferably curved outward, and at the point 3' is sub-. stantially in the line of the traverse ,of the lower end of the seed-carrier, hereinbefore described. On the rear wall of this funnel J there is mounted atransverse rock-shaft J provided with straight springarms J which when turned into the position shown in Fig.

'7 form supports for the lower end of a bag.

The rock-shaft J is also provided with curved springgripping arms J which, when turned into the osition shown in Fig. 7, serve to grip the owerend of a bag (shown in dotted lines a) resting on the supports J between them and the rear wall at the point 3', as illustrated in Fig. 7. These su porting arms J and the gripping arms 4 operate through an o ening in the rear wall J of the funnel and are adapted by the rotation of the rock-shaft J to be with drawn through the opening 3' in the rear wall of thefunnel, so as to release the bag and allow it to ass down therethrough. The rock-shaft J 1S preferably operated by means of a bevel-gear K thereon which intermeshes with a like bevel-gear K on the upper end of a shaft K which is driven by means of a bevel gear K and connected therewith by means of an ordinary spline and groove, so that the shaft'K will slide vertically therein. The gear K is driven a bevel-gear K on the end of a horizontal rock-shaft 7c mountedin bearings k k on the machine frame A, and on the o posite end of the shaft is there is a s ur-gear 2 which intermeshes with a vertica ly movingrack-bar k, as clearly shown in Fig. 7, which rack-bar k is actuatedby a cam L on the end of the main driving shaft M of the machine as is clearly shown in Fig. 1. This cam L is so shaped that it wil operate the gripping mechanism to grip a bag while the seed-carrier gummed and sealed, as hereinafter set forth, and then the retracting spring k on the rackbar 76 will operate said mechanism to release the bag. It will also be observed that the gripping mechanism being so mounted as to be vertically adjustable, can be adjusted to grip the lower end of any length of bag when the flap anvil, ereinafter describe and in osition to be turned down upon and scale to the shorter ply of the bag.

The gumming mechanism of this machine consists substantially of a pair of arms N N joined together by a cross-piece N at their upper ends, forming a gum-lever as clearly shown in Fig. 2. r The lower ends of the arms N N are provide with journals pivoted in bearings n n on t e frame A. In the upper ends of the arms '=N N directly under the cross-piece N there is pivoted a semi-rotatable gummer-bladeN (see Figs. 1 and 7 havof such bag is opposite the sealing V 30 I v N a laterally projecting arm N with which lever.

in being ing on the outer end of one ofits journals a' small spur-gear n, and mounted on one of the arms N there is a sliding bar N provided at its upper end with a rack-gear n intermesh'ing-with the spur-gear n, and on the lower end of said sliding bar N there is a stud n which engages in a cam-slot n in a plate N secured to the frame. On the lower parts of the front edges of the arms N ,N of the gum-lever, there is secured a U-shaped clamping spring N the transverse portion a of which is adapted to contact with the'lower portion of the sealing anvil hereinafter described. The paste-tank O is of the usual construction, and is provided with a pasteroller O mounted and rotatable therein, and on the outer end of one of the ournals there of there is a clutch flange and a clutch arm 0 which is actuated by a link 0, one end of which is connected with a jaw 0 on the clutch arm 0 and the other end with the lower part of the gummer-arm N, so that the movement of the gummer-lever arms back and forth, operates through the link 0 the clutch jaw 0 the clutch arm 0 and the clutch flange 0* to rotate the paste-roller a short distance at each rearward movement of thegummer- For operating the gumming mechanism there 1s on the lower end of one of the arms the lower end of a connecting rod P is connected, as clearly shown in Fig. 9, which eX- tends to and is actuated in one direction by a cam L on the shaft M, and in the opposite direction by a spring P (shown in Fig. 9). This yielding connection is preferably formed by making a slot p in the rod P, which operates on a stud-pin n on the arm N, a spring rovided which acts to retain the slot p an the stud n in the normal position shown in Fig. 9.

In operation the g umming mechanism when in the position shown in dotted lines in Fig. 1, has the edge of the gumming-blade turned downward in contact with the gumming roller 0', and at this time inthe operation of the machine, the seed-carrier hereinbefore described has carried a bag down to the roper position to be folded, and. as in its furt er operation the seed carrier is withdrawn from the bag, the action of the cam L on the gumming mechanism moves the gummer-lever forward until the spring clamp N contacts with the bag and pushes the upper portion thereof against the sealing anvil;

meanwhile during this forward movement of. the gummer-lever, the ummer-blade N by the action of the mec anism' hereinbefore described, has been turned upward into the horizontal position shown inFigs. 1 and 7, and the further traverse of the gummer-lever brings the edge of the gummer bIade N into contact with the shorter ply of the bag and presses it against the sealing anvil with a on the face of the anvil Q. Infa recess q in lated to fill the slot g and complete the face seaaae the further operation of the mechanism, from the shape of the cam L, the gummer-lever is then immediately retracted by the action of the spring P until it reaches substantially the position shown in Fig. 1, which leaves the spring clamp N still holding the upper end of the bag against the sealing anvil, in which position the glimmer-lever remains until the sealing jaw of the sealing mechanism hereinafter described, has turned the bag-flap down u on the gummed surface of the shorter p y of the bag and sealed it, at which time the shape of the cam L permits the action of the spring P to return the gummerlever to its normal position, as shown in dotted lines in Fig. 1. I

The sealing mechanism of this machine consists substantially of an u right anvil face Q on the upright A as is clear y shown in Figs. 1 and 10. In this anvil face there is a transverse slot q into which the gummer-blade N passes in case there is no bag in place to be gummed so as to prevent the deposit of gum the standard A back of thea'nvil, there is an oblong block Q which has its lower edge piv-' oted in the recess 9 so that it can be oscilof the anvil Q, and arms 9 on the block Q project outwardly and downwardly throu h slots 9' in the anvil, and are adapted'to e engaged by a bag pressed against the face of the anvil, and rock the block Q so as to close the slot 4 during the action of the gummerblade on the bag, as clearly shown in Fig. 10, and so long as the spring clamp on the gummer-lever holds the bag in contact with the anvil, the .block Q remains in this position.

For turning the bag-flap down upon the shorter plyflof the bag and completing the sealing operation, the jaw R is rigidly secured on arms R which pass down at each side of the standard ,A'. These arms R are provided with slots 1 which engage studs 7" on the'standard A, andthelower ends of the arms R arej'connected together by means of a transverse'rod R operating in a slot 1 in the standard A (as shown by full and dotted lines in Figs l 7 and 10) by means of which as'the jaw structure travels downward it first moves vertically some distance, and finally diagonally toward the anvil until it meets the face thereof, and during this traverse th edges 1' of the arms R engage lugs on the ends of the block Q and hold it firm y in position while the jaw R acts against the anvil face to seal the bag.

For operating the jaw R there is a rockshaft S journaled in the upright A, havmg an arm thereon formed preferably of two sections, one, S, rigidly secured to the rock: shaft, and the other S pivoted thereto, which sections of the arm embrace the rod R be- 130 tween their ends. The section S of the arm has a downwardly hooked extension S which serves as a support for a spiral spring S between it and the end of the section S of the arm (see Fig. 7 so as to rovide some yield to the pressure of the jaw ft against the anvil face Q of the sealing anvil. The rock-shaft S is provided with a lever S which engages a suitably shaped cam L on the driving shaft M of the machine, the rotation of which cam operates the mechanism to bring the sealing jaw R against the face Q of the sealing anvil, and a spring S on the rock-shaft S operates thereon to return the sealing jaw R to its normal upraised position; these parts being clearly shown in Figs. 6 and 7.

On the frame A at the side of the guides H there is secured an air-pump T of ordinary construction, having a piston rod T connected to an arm H on the cross-head H. From the upper part of the air-pump, a pipe T extends so that the open end thereof will direct the air discharged therefrom across the mouth of a bag when in position to be acted upon by the gumming mechanism hereinbefore described, and operate during the upward movement of the seed-carrier to blow away any dust or other matters thereabout which might be taken up by the gummer-- blade and accumulate thereon so as to foul it;

In the lower end of the pump-barrel an inlet t is provided over which an ordinary flap valve 15 operates to close the opening t during the downward traverse of the pump piston, and through the valve there is a small con tracted opening t through which the air in the pump-barrel, below the piston therein, slowly escapes during the downward movement of the pump-piston by which means the air-pump T also operates as a dash-potto counterbalance the weight of the cross-head ll and its connected mechanism, during the downward traverse thereof.

The mechanism for operating the mechanism hereinbefore described preferably consists substantially in a drivingshaft M mounted on the machine frame and carrying on its inner end the cams L ,L L operating the gripping, asting and sealing mechanisms as herein efore described. This shaft is provided with a band wheel M to which power from any suitable sourcecan be applied so as to rotate it in the direction of the arrow m. On this shaft M there is also a ear-wheel M which'intermeshes with a like b l n gearwheel I on the shaft 1 which carries the crank disk 1', operating the seed-carrier mechanism through intermediate mechanism as hereinbefore described. There is also a sprocketavheel e on the shaft 1 which, through the sprocketchain 6 operates the measuring mechanism hereinbefore described.

In operation the several parts of the mechanism hereinbefore described, cooperate with each other substantially in the following manner: A quantity of seed or other material being placed in the seed-rece tacle E, the cups E being properly adjuste to measure the desired quantity of seed, bags being placed in the bag-holder with their open ends up and the shorter plies thereof outward, and suitable paste or gum having been placed in the gum tank 0, the mechanism is started by meansof the driving Wheel M being rotated in the direction of the arrow. When the seed-carrier arrives at the uppermost point of its traverse, one of the measuring cups E, having dipped up a charge from the seed-receptacle, deposits it through the nozzle E into the seed-carrier the continued operation of the machine then moves the seed-carrier downward, and the lower end f thereof enters the 0 en end of the outermost bag on the bag-hol er and moves downward within the bag until it has reached the bottom thereof, when its further movement turns the flap B on the bag-holder downward, removes the bag from the bag-holder and carries it downward, the flap B meanwhile pressing the bag between it and the seed-carrier and thus preventingv the displacement of the bag thereon until it has completed its downward traverse; meanwhile the bag-supports J by the action of the gripper mechanism, having been raised into place with the lower end of the bag restiing thereon, the further action of the gripping mechanism causes the grippers J* to grip the lower end of the bag against the side of the funnel J and hold it firmly; then the further action of the mechanism starts the seed-carrier on its upward traverse, and soon after it starts upward it is opened by the mechanism-hereinbefore described, so that the seed therein passes out of it into the bag. As the seedcarrier, in its upward traverse, is passing out of the upper end of the bag, the cam L operating the gummer lever raises it from its normal position where its gummer-blade is in contact with. the asteroll 0, (as shown in dotted lines in ig. 1) and moves it toward the bag, and the spring clamp N thereon forces the up er art of the bag against the sealing anvil 5, w iich operates to turn the block Q forward and c ose the slot q in the face of the anvil, the gummerlever continuing its forward-traverse then contacts with the shorter ply of the bag, depositing a supply of gum thereon, and then on account of the shapeof the cam L, gummerdever to substantially the position shown in Figs. 1 and 7, where it remains with the spring clamp N holding the'upper part of the gummed bag against the face of the anvil, the cam L now acting to move the sealing bar downward, turns the flap of the bag down upon the gummed surface and clamps it firmly against the face of the sealthe spring P immediately retracts theing anvil; as soon as this is accomplished, the cam L releases the bag-supporting and grip ping mechanism, and the retracting spring lc erates on the mechanism to move them bac: out of the funnel J, and atthe same time the cam Lf releases the paster lever, which is then at once returned to its normal position with the asting blade in contact with the paste-r01 0. As soon as the spring clamp N moves back from the bag, 13

e cam L immediately releases the sealing jaw R, and the retracting spring S operating upon the mechanism moves the sealing bar R up to its normal'position, and'the filled andsealed bag is thereby released and falls down through the funnel J. Meanwhile the seed-carrier has returned to its uppermost position again, ready, to operate as herein efore described.

We have thus described our invention so as to enable others to construct and operate the same, but it is obvious to those skilled in the art, that many parts thereof may be considerably modified in their construction and arrangement without departing from the spirit 'of our invention; therefore we do not desire to restrict our invention to the exact construction and arrangement of mechanism shown and described herein, as
